Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 35,503,139, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 35,503,139 | |
| -1 | -35,503,139 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 35,503,139.
Example:
1 x 35,503,139 = 35,503,139
and
-1 x -35,503,139 = 35,503,139
Notice both answers equal 35,503,139
With that explanation out of the way, let's continue. Next, we take the number 35,503,139 and divide it by 2:
35,503,139 ÷ 2 = 17,751,569.5
If the quotient is a whole number, then 2 and 17,751,569.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 35,503,139 | |
| -1 | -35,503,139 |
Now, we try dividing 35,503,139 by 3:
35,503,139 ÷ 3 = 11,834,379.6667
If the quotient is a whole number, then 3 and 11,834,379.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 35,503,139 | |
| -1 | -35,503,139 |
Let's try dividing by 4:
35,503,139 ÷ 4 = 8,875,784.75
If the quotient is a whole number, then 4 and 8,875,784.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 35,503,139 | |
| -1 | 35,503,139 |
If you did it right, you will end up with this table:
| 1 | 7 | 137 | 959 | 37,021 | 259,147 | 5,071,877 | 35,503,139 |
| -1 | -7 | -137 | -959 | -37,021 | -259,147 | -5,071,877 | -35,503,139 |
